I see this was not possible six years ago:

Did the Oracle got smarter? Is it possible to do this now?

One of our developers team member had created a Anonymous block program to do something in the Database, and he forgotten and terminated the session without confirming the program's status, whether it was fully ran or not.
Is there any way to check out the status of this, which happened yesterday?

I know those value could be get from command line , but could we get the values of Listener and Read only by SQL/PlSQL? So I can get it through the query of DB.

I want to load lakhs of records into a table. My problem is when after loading the ¼ of records my process is abend due to the size of my rollback segment area. I don't have an option to increase it. So, Is there any way to go for intermediate commits when I am using the imp or sqlldr utilities to load the entire data without abend?

I have a requirement to read flat text file(around 15000 lines) residing at a client location from DB server and write into a table in One cell.
I tried UTL_FILE and DBMS_LOB but, i am not able to access client location to read the file as it reads path from Oracle Directory.
eg.
my client path is 198.168.1.1 and my DB server is in unix say 192.168.1.10.
file location is: \192.168.1.1shareabc.txt
So I created One Oracle directory as MY_DIR having DIRECTORY_PATH as '\192.168.1.1share'.
But both UTL_FILE and DBMS_LOB is not able to access the file.
Error Message:
-------------
Unable to process CLOB -22288 ~ ORA-22288: file or LOB operation FILEOPEN
failed
No such file or directory
Few Details for reference:
-------------------------
File Location: \192.168.1.1shareabc.txt
Unix DB Server location: 192.168.1.10
Table : Test (filename varchar2(30), Content CLOB)
Oracle Dir: MYDIR
Directory_Path: \192.168.1.1share

I've a question regarding difference of character sets, while taking a export(logical backup) of database on directly to server(linux RHEL 2.1 AS) and export on a client (windows xp prof machine, where only a oracle 9i client is installed). On server it seems to fine and okay, but on client node i'm getting following error for almost all tables.
EXP-00091: Exporting questionable statistics.
My question is :
[1] Is it creating any sort of problem, if later on i import the data which was taken from client node.
[2] Why there is a difference(marginal) in dump(.dmp) file size.
[3] Is there any way to overcome it, or it is the natural behave of it. Means not a problem.
[4] If i'm using a long or blob as datatype for some of my table,is they have any problem if i persist like above.
Additional Information about character sets On server node :
Export done in US7ASCII character set and AL16UTF16 NCHAR character set server uses WE8ISO8859P1 character set (possible charset conversion)
On client node :
Export done in WE8MSWIN1252 character set and AL16UTF16 NCHAR character set server uses US7ASCII character set (possible charset conversion)

I'm importing data from SQL Server to Oracle. I used BCP to export the data from SQL Server. Below is the 1st record of table trlc from the csv file.
trlc.CSV
11032|100|Wman| | |2008-02-08| |
Using SQL Loader to import into Oracle:
TRLC table in Oracle database:
est_no varchar2(10) default ' '
right_no number(4) default 0
maj_auth varchar2(15) default ' '
weight varchar2(10) default ' '
idm_ht varchar2(8) default ' '
c_date date
P_tkt varchar2(5) default ' '
sqlldr user/pwd@db02 control=trlc.ctl log=trlc.log
trlc.ctL:
load data
infile 'trlc.csv'
replace
into table trlc
fields TERMINATED BY '|'
TRAILING NULLCOLS
(est_no,right_no,maj_auth,weight,idm_ht,c_date,P_tkt)
The rows get inserted successfully. But the result sets are different, for example: When I do a select in SQL Server,'select len(weight) from trlc;' , I get the length as 0. But when I do a select in oracle database, I get the length as 1. Also, the result set varies for the query below:
select * from trlc where weight=' ';
(SQL Server returns 1 row but Oracle returns no rows)
Do I need to mention any conversion code for the weight field to accept ' ' value?

Here are the cards I've been dealt:
I've inherited a 10.2.0.1.0 instance running on a windows 2003 box; running fine, no problems other than system has been in production since 2005 and has gotten pretty old and tired. This old box has one tablespace on it... called "gateway".
I've installed 11.2.0.1 on a new (Windows 2008 R2 Enterprise 64-bit) server and created an empty database also called "gateway".
Now to move the data and views, objects, everything.
I've read up on a variety of migration techniques (oops, I mean "upgradation" LOL) and can follow the steps...
In short, I want to pull everything off of server a (10.2) and put it into production on server b (11.2). There seems to be quit a few options.
1. install 10.2 on my NEW server (server b), move the data over and get everything running, then install 11.2 and have it upgrade the database as part of the installation process.
2. drop the empty tablespace on server b, stop the database on server a, copy the files over from the old to the new home, run DBUA or set the compatibility attribute...
3. run some type of server a to server b utility that can bridge the two over the network. Some type of mirroring technique?
4. run file export scripts on server a, copy files to server b and run various import scripts
I tend to think that option 3 would be the best because both instances are in great health and are running right now. Is there a mechanism that allows the 11.2 instance to see and upgrade from a different server?

any other utilities that we can use to load data from our PROD server (10g) to DEV server (9i)? I've read some related topics here that it's not possible to import from a HIGHER to LOWER versions of Oracle. We've tried (many times) EXPorting selected tables from the 10g dB, then IMPort it to the 9i dB and we've haven't succeeded anyhow. PROD & DEV have a different schema/owner but the same table structures.

I have issue of TABLESPACES on test instance. Tablespace files are TEMP1,TEMP2 and APPS_UNDOTS1. Initially TEMP1 and TEMP2 were of 4 GB but now the have grown to 32 GB each respectively. Resulting an occupied space of 64 GB on test server. I want to reuse that space on test instance as those tablespaces never crosses used space of 1%. Reason of this problem was my DBA set AUTOEXTEND as ON for tablespaces.

is there any way to alter only max value in sequence without specifying the max value.
i know we can alter it like :
-- Alter sequence
alter sequence TEST_SEQ
maxvalue 99999999;
can we alter it without providing the max value and let oracle choose default value for the same, same as we can do it when creating a new sequence.

I have a table Employee which gets updated and Inserted very frequently. Wanted to increase the PCTFREE value for this table
select table_name,pct_free,chain_cnt from user_tables
where table_name='EMPLOYEE'
EMPLOYEE NULL 0
is the output. I altered the pctfree like below
ALTER TABLE EMPLOYEE PCTFREE 30
and I can see Table altered but the value is not reflecting in above command again. Where else I should alter the value and cross check that value is changed.
